 If we do this right this module could replace IGNET and ARTV and could be used
 clients to sync mailboxes and calendars etc.

+We should care a bit about performance here. 
+-> not use the sendcommand/ctdl_ipc here.
+To gain performance, (profiler says...) we musn't read byte by byte aymore, but read blocks.
+thus the out/input format should be a bit similar to the http chunked mode, sending blobs of 
+n bytes at once.
+Probably up 64K windows are apropriate here. it could look like that:
+<line by line mode>
+Messageheader=blabla
+AnotherMessageHeader=blub
+DATA CHUNK 65535

+CHUNK 2344
+< 2344 bytes; probably the overlaps of the message. >
