Can map server send feature data/vector data to the client?

Hi,

a little off-topic but I've been getting lat/long and name of points in a
layer for the mouse-over function. Its quite possible to request wfs on a
small amount of data (~300 points). On a shapefile it takes around .2-3
seconds. Luckily the users can only see the first 10-20 chars of the string
of formatted data of all the points, the rest invisible in view-source mode.
