You've bolded the point about NGP players playing against PS3 players. That isn't in any way tied to the graphics calls the game is using! That's just a netowrk protocol and access to the same PSN servers. It could be achieved with a DirectX PC playing with a PSGL-version of the same game on PS3.
Sorry if I gave a wrong impression. There were two points in my first message and one of them had to do with cross platform play and the second with remote play. The quote in bold supported the first.
Still, regards OGL, it makes sense to use a uniform library across devices rather than an interrim format that has to be compiled. I expect PSS games on PS3 to be identical to NGP versions save for higher resolution, like Minis, PSS being the new framework to replace Minis with a far more effective engine. Thus PSS titles would happily run within the limitations of OpenGL on PS3. If Sony are going to write a PSS compiler for PS3, they may as well write a full OGL implementation than write a conversion between PSS's OpenGL calls and lower level access of PS3's hardware.
Thanks for confirming the logic on this one point OpenGL on the PS3.
With Cross platform, OpenGL is, I think, a given. With Open GL support on the PS3 it would be easily possible to support remote play, a touted feature of the PSP but never fully developed. This is so obvious that the author of the quote thought it implied in Sony press releases.
Beyond remote play, the same application could support a remote XMB screen and access to all PS3 features like a remote desktop application does for PCs (IF the XMB is rewritten with OpenGL calls, a rewrite which I think is coming for the Webkit port and possibly to allow PSS access/ports . Many of the Open source libraries for the NGP will probably be used and they probably take advantage of OpenGL.).
It's a feature I think would help sell the NGP. Off topic, I know, but the logic chain is immediate.
It should also be easy to write remote control/play applications for various CE products and services through PSS suite given "Standards" (hardware and software). Sony has been pushing for "Standards" and is a part of multiple non-profit Organizations developing standards for the industry. A list of those organizations might give us an idea of what is planned for use with PS Suite.
Google is also behind Open Source standards and has been purchasing companies with what they must believe is critical IP and releasing it as Open Source.

"PlayStation Move Coming To PC" An attempt to get the "Move" accepted as a standard controller interface on the PC for the eventual PS Suite PC platform?
PS Suite to my mind is not a cross platform language or rather not just the cross platform language "C" but a
SUITE of Software tools and processes relying heavily on Hardware and Software standards. Those Hardware and Software standards are what the PS Certified logo is all about. For hardware, we currently have a subset of the NGP hardware set and with the above "Move" coming to the PC another possible, combining touch screen surface management standards (from Android) we could have right or left hand rotation of the move controller being a pinch or expand. For Software Standards we already have many open Source Standards like HTML5, Ultraviolet model, DRM, Plug and Play, Posix & "C", OpenGL, CE-HTML, HbbTV, W3C. GDC or E3 may confirm these for PS Suite and possibly add more.
It's possible that consumers may rely on the Android and PS Certified Logo as well as the Ultraviolet Logo to feel comfortable with future Hardware platform and Media purchases.
