Are we allowed to talk about Homebrew here?

I'm just wondering, cos I know its OBVIOUSLY against the rules to talk about copying games and whatnot, but I'm wondering if we're allowed to talk about the Homebrew hacks for the PSP.
For those that don't know, Homebrew are programs that explot unsigned code in the PSP (which Sony deal with in later firmware/patches) allowing you to play full games you can obtain online (have I said too much?).
However, it also allows you to run other homebrew applications which aren't so.. illegal. Such as turning your PSP into a GPS system.
That in mind, are we allowed to talk about it here?
