I pondered this briefly and purchased the UltraEdit/UE3 bundle,

UltraEdit32 just released a PortableApps.com compatible version; you might ask them if you can trade your U3 version for one that integrates with the PortableApps.com suite and launcher if you prefer that. I talked to the PortableApps.com lead at OSCON and he specifically mentioned UltraEdit32 as one of the partners for PortableApps.com's commercial launch.
