Hi Ivan,
You can call tracker without any special registration. We provide  
libtracker-client as a convenience for C developers (and our command  
line tools), wrapping some DBus code and encoding help functions.
So, if your application is in C, use libtracker-client. If it is in  
vala or python or other languages with easier DBus integration, go  
for the DBus API.

Even in higher level languages, it would be great to be able to use  
the commodities provided by tracker-client and use DBus transparently.
My current use case is making a tracker frontend using SeedKit. based  
on one of the many existing web-based semantic/linked-data browsers.
This could be achieved for most bindings by making tracker-client g- 
instrospectable, is there any effort in this direction ? Would patches  
be welcomed ?

Yes

 From what I understand your are investigating a direct access to  
Tracker with your own binary IPC/RMI protocol, tracker-client could  
hide that transition to client apps developers, being in C or  higher  
level languages.

Agree. But if we do provide a custom IPC method, then it'll probably
still be possible to continue using the old over-DBus less fast
SparqlQuery.

You can look here how it might look (DBus object is called
TrackerSteroids in this experiment). Note the "experiment" in the branch
name. No promises if you start working with this!
