The online platform for Enscape users to submit, vote, and collaborate on creative suggestions.
.exe files have a hard limit of 2GB set by Windows (according to your help dept, I didn't look further into this). Most of my models get beyond that before a project is finished. I wonder if it would be possible to create a .bin file or some standard format for the data of an enscape session that could be interpreted by a runtime environment, so for instance there is an "enscape viewer app" that could be a standalone app on either windows or OSX, that app could then be used to open standalone enscape files, so a person (consultant, client, etc) would install enscape viewer on their machine, then be able to open any session exported from enscape. The limitations would be entirely hardware dependent, the app could even just give a warning, something like "the hardware on this computer will only allow draft version, to see in full resolution please install on a computer with [link to suggested minimum and ideal requirements]"
If something like this isn't possible, perhaps a subscription service to high quality web based viewer. Something like a traditional render farm that will host enscape sessions and stream video back to client browser.
