WM Marketplace - issues when rom upgrading/changing devices

[fredcatsmommy]

has anybody figured out where cab files are downloaded when you purchase apps from the Marketplace? For those of us that frequently flash new roms, I'd much rather have those programs autoinstalled using sashimi or some other autoinstaller rather than having to re-install from Marketplace. This is also an issue if you change devices; I've heard that Marketplace will reinstall apps based upon your device id. So I'd rather have the cabs.
