[news.eclipse.platform.rcp] Re: Updating a RCP through an Eclipse applic

[Pascal Rapicault <pascal@xxxxxxxxxx>]

For the simple case, if you want to reuse update manager and features, 
then the server can simply make the new plugins it got from the internet 
available on a local update site. Then, when the client starts it checks 
the availability of the new features, and install what it is necessary 
and run. Note that installing a new feature does not delete the old one 
(this is important).

For the second case, similarly to the previous case, your app could 
check the versions available on the server. In case the server has an 
old version, then you need to configure the appropriate version and 
deconfigure inappropriate ones.

All those operations can be implemented using the udpate.core APIs.
