The speed is far from optimal, but I don't mind it too much.
I've recently recorded a project for a local singer, who wants to take the tracks home on CD-R to mix in (ouch) cubase, instead of going through my Soundtracs console. Anyway, at the end of each session, I ftp the track to my PC and then burn it on CD-R for him.
It takes some time, but I always ending up putting the mics back in the cabinet, making notes of the session, talking to him about the tracks we cut, unplugging all mic cables etc etc.
So, by the time we're done, the CD-R is too.
