Quotas with Supporter & Upgrades plugins.

I'm running into some trouble with both the Supporter and Upgrades plugins installed and active.

Primarily, the Supporter plugin suits our business model, but not being a large company, we're a bit tight on disk space, so we've set a minimal amount of space for free users, and a 1GB cap for Supporters using the plugin. We would, however, like to be able to offer 10GB, 50GB, and 100GB packages to the select few Supporters who absolutely need that extra space.

The apparent solution was to use the Upgrades plugin in conjunction, but, while each plugin works beautifully on its own, if one of our Supporter members tries to further upgrade their account using Upgrades, their "upgrade" gets clobbered by their smaller Supporter quota.

Any idea on a fix?
Would it be possible to integrate this functionality into the Supporter plugin, and get rid of the annoying $ vs credits inconsistency at the same time?

Thanks for your help in advance.

Nice new site design.
