Yes, a few people have asked for some method of supporting this use-case so we
definitely want to make it work. Now may not be the best time to work on it as
the package download code in opkg master is currently in flux and the current
work needs finishing. I'm hoping to finish tidying this up soon and then there
will be a stable base on which to add this feature.

I'd suggest filing an enhancement request at
https://code.google.com/p/opkg/issues/.

If you'd like to discuss the details of how this could be implemented within
opkg or contribute patches yourself then that's best discussed on the opkg
mailing list at opkg-devel at googlegroups.com.

Cheers,
