Links to the retro/revival Instant Messaging platforms/clients:
Escargot — What's old... is new again! Escargot is a service that makes various versions of MSN Messenger and Windows Live Messenger work again. [NOTE: NINA, Escargot's sister project, was shut down due to the legal issues]
SpaceHey IM — SpaceHey's instant messaging platform... and analogue to MyspaceIM.
KICQ — it's an ICQ analogue, based on the old OSCAR protocol. It's based on the open-source project IserverD... so that is, it's the same ICQ (well, almost) that you had on your phone in 2008!
