Hmm yeah. Thing is if I still had ddi subscription I could make them there and give out .monster files, which people could use with any software, not just masterplan. But that does have the side effect of requiring me to give more money to WOTC when they've basically written 4e off.
As for updated math, I have the first two acts complete. I'll set up a dropbox account and share the library files tonight when I get home from work.
