Joe, I'm just seeing If I could grab certain data from a Web service
method (like on a drill thru). That would be cool. Thanks everyone for
the replies.

Doomed!

the drillthrough return detail from the database, so again, you can't return
data from an external source.

you can create some actions to open a webpage where you consume the
webservice. (with some parameters coming from the cube)
you can also consume a webservice in Reporting Services as a datasource, and
you can use open the report as an action from your cube.
so instead of a drillthrough command, the user will execute an action which
open the report or the webpage

in fact, the drillthrough is just another action type in SSAS.

do you use your own client application?
or do you use an existing olap client tool?
