that communicated with one another via a data synchronization element. However
this required the same business rules to exist and be maintained in two different
applications. The new goal is to write one set of business objects (EJBs)

a feel for what the performance implications are for running an app server
on a laptop (or PDA?!) or if there are suitable alternative technologies
