Actually, the longtable package supports captions too, and the caption 
package (which allows further customization, 
http://www.ctan.org/pkg/caption) explicitly supports longtable:
---------
Package support
The caption package was adapted to the following packages which deals 
with captions, too:
float, floatflt, fltpage, hyperref, hypcap, listings, longtable, 
picinpar, picins, rotating, setspace, sidecap, subfigure, supertabular, 
threeparttable, wrapfig, and xtab
---------
99% of our tables use ordinary tables, but 1% of our tables won't fit on 
a single page and require longtable.  These need captions the same way 
regular tables do (there's also a continuation caption on the second and 
following pages of longtables).  I didn't show a bunch of rows in my 
example to keep it minimal; the actual table where we first noticed the 
problem was just over a page in length.
