IIRC, PRO-CFW is signed and can be executed directly from OFW 6.60, so I'm thinking it's still possible
No, its not. The fake-np trick was removed on PSP OFW 6.60, not homebrew signing. The PSVita OFW 6.60 has changed the encryption inside the emulator, so doing so doesn't work. Besides, you don't have an XMB in the emulator, where would you run the signed homebrew from?

What's wandering around my head is this: what if they have 2 versions of PSP games on PSNStore, now? What if the Store detects what console it is, and sends the PSP-encrypted (with the key discovered by Mathieulh) to the PSP, and a second version (with different encryption) to the PSVita. It's a LOT of useless management and I doubt Sony works like that, but maybe they would just to piss hackers off...
I'm quite certain this is exactly what is going on. Were they not, my PSPgo games wouldn't work anymore, for lack of the decryption key on the games available. (I can still NPD even newly redownloaded games with from MediaGo, so, its the old key on mine.)
The other other possibility is "on-the-fly" games signing per download, and that would be even more cumbersome server-wise.
