WOWZAALEX Just to correct a misconception, Wowza Pro does not cost the same as FMS. Wowza Pro Unlimited edition is priced at $995. It is a fully interactive Flash media server just like Flash Media Interactive Server (FMIS) which is priced at $4500. So Wowza Pro is 75% less.

A free Wowza Pro10 edition is in fact intended for developers. So calling it a developers' edition is fair.
