i did not receive any further replies than the ones i posted... and i didn't mention DRM for the moment.
even if i had gotten more replies, i would encourage you to write as well ; the more people manifest their wishes to penguin, the more likely penguin is to begin to take us seriously.
if you do write, feel free to dig up this thread whenever you like to tell us all about it. i for one am interested.
if you look near the start of the thread there are a couple of email addresses you can try, unless you find something more suited (in which case, please post the one(s) you find).
