If the publisher were genuinely interested in an actual portable version and wanted to promote and support it alongside, it would be a different story.

I'm going to have my hands full getting Opera 16 up and running (our assumed target when the new Opera is usable enough to replace the old one) without taking on a niche browser like Comodo that doesn't seem to bring much to the table.

This needs to be adapted for each implementation of Chromium/Blink and then maintained on an ongoing basis. The only way around this is to use a custom-built password portablizer like we do in the Format packages of Google Chrome Portable, Iron Portable and Chromium Portable (which will become official shortly). All of them are mislabeled as portable when a major feature (saved passwords) doesn't work portably at all. This includes Opera 15's built-in 'portable' mode, Iron's official zipped 'portable' version, X-Chromium from WinPenPack, Comodo Dragon's 'portable' install, etc. As with all 'portable' versions of Chrome-based browsers from other entities, saved passwords are locked to a single PC and won't work as you move around.
