XARSIM - Text, Voice & Video Telephony and Messaging
XARSIM, the Xrossover Address Resolution,
Stored and Instant Messaging protocol is designed
to be used even (or especially) within typical SoHo environment -
and to be hosted by the users themselves. All definitions and standards
shall be free(ly available).
After struggeling with all current Voice-over-IP (VoIP) protocols
(SIP, H.323, Nortel's proprietary UniSTIM) and RTP/RTCP, after E-Mail is increasingly
approaching inusability (with VoIP hard on its heels), it was time to
develop a protocol that adresses today's needs instead of wasting time
and effort in throwing patch after patch against a frail (and failing)
corpse.
XARSIM was designed to be reliable, fast, slim, decentral and flexible - and
turned out to be quite universal, too.

Changed (compacted) Messaging and Notirfication Protocol
- Moving from a "cleartext" protocol to a binary messaging protovol:
more compact, easier pasring and thus increased security and speed
(less overhead).
To keep the overall system consistent the notification protocol was
adapted accordingly.
