If you can adapt it to rtpp_2_0 that would be great. This is our latest
production code and it's pretty much superset of the 1.x feature and
performance wise. I've just pushed some fixes to get it compile cleanly on
Ubuntu using just GNU make.
Are you guys registered on github? I've been trying to add you to the
repository ACL list but could not find anyone. Jev is off for few days, but
he should be back tomorrow to finish migration of the website etc.
Thanks!
