Hi Greg,

>From memory....

XBAP needs to run on a windows box with recent IE and full dot net
framework running on it.
Silverlight can run on any box with any browser and the Silverlight plug in
installed.

So Silverlight will (should) give you a far greater reach.

We just need to know what Microsoft's ongoing support plans are for
Silverlight.
A few years ago the plan looked to me like:
 - all main desktop OS's,
 - all main desktop browsers
 - Windows and Nokia phones
 - and anything else they can get it on

For now at least I have wound back my Silverlight investment until we hear
some clear (positive) direction from Microsoft.

All the best
Greg H
