I have a market data application which needs to show live price updates in a
table. This table will refresh every 10-15 seconds. The table is read-only.

Currently, in ASP, I refresh the frame itself, which works fine. However, I
now need to highlight a changed price, as it happens, using some kind of
highlight-fade DHTML sequence..

Hunting around, there seem to be two ways to do this:
1. Use a Web service behaviour
2. Use DotNet remoting

Has anyone grappled with live data refreshes yet? So much of the
documentation assumes there will always be some kind of user response (push
a "refresh" button, edit a record etc)...there isn't a lot on what the
_best_ way to do dynamically refresh a dataset is...without any interaction
and using a timer or something....

Any help appreciated
