Is it possible to connect the MTi/MTx, MTi-G or Xbus system to a PocketPC?

Yes, most PocketPC's support standard RS232 input (mostly with supplied RS232 sync cable) so you can develop software for the PocketPC using  Xsens' Low-Level Communication or CMT (levels 1 to 3) to configure and retrieve data from the motion trackers. Using the Xbus Master you can also easily connect to a PocketPC using BlueTooth. Contact Xsens for information on serial cables.
