After a bit longer time I succeeded in forcing myself to make an update

It's just an update to latest(12166) revision, so do not expect any new functionality. Anyway, here you are, enjoy.
EDIT: Uploaded bad file, this one have one issue fixed, and bumped savegame version, should be able to load trunk save games.
EDIT: Even that one was not OK, this one should.
EDIT: Update to r12188 and a patch for tracksharing combined with yapp, it seemed to work on first sight, but it wasn't thoroughly tested, so desyncs are possible.
EDIT: This update contains just a bit more changes:
- Update to r12209
- Cost will be set for 1000 ton tiles
- Minimum cost charged in case you travelled > 0 ton tiles on foreign track is for 1000 ton tiles.
- Vehicle profit should be correct now.
EDIT: I combined track sharing with Gonozal's patch pack. When used in net game with PaxDest patch it occasionally desyncs but this happens AFAIK also with clean PaxDest patch.
