First of all, let me say how excited I am to see the first commercial marketplace that spans multiple grids! Thanks, Kitely, for doing this amazing bit of coding!

Obviously I had to try out delivery to my company's private grid (yes, we also have an island on Kitely for public visits — a copy of the private content gets sent to the public island on Kitely occasionally).
Our grid is very, uh, "bleeding edge", and this might be the reason that things do not work yet. We're running 0.8.0 Dev, usually the latest nightly build (there are reasons for that, but that's another story).
So the first step is to validate delivery. And here I've stumbled upon an issue: the Notecard with the code does not get delivered... but clearly it's "almost" there. Here is what I get on the logs:
22:34:14 - [HG SUITCASE INVENTORY SERVICE]: Found no folder for type Notecard for user 35c965ac-0b37-4b36-968a-6dbdc127a544
22:34:15 - [HG SUITCASE INVENTORY SERVICE]: GetRootFolder for 35c965ac-0b37-4b36-968a-6dbdc127a544
That UUID is definitely the correct one for my avatar on that grid.
The folder "Notecard" is certainly there... I've added a "test" notecard, so just to make sure there was something in it.
I understand that this is pretty much cryptic. Apparently, Kitely has no problem in contacting our grid and informing that they're attempting the delivery of a "Notecard". But, strangely enough, this "Notecard" is not seen as a Notecard?
The only explanation I have is that 0.8.0 Dev has different types than 0.7.6. Of course I didn't notice any difference when doing the migration, because all migrations also update the database. Still, I have no idea if that's the case; I'm just widely speculating.
I know I have no firewall issues... because usually I log in to that grid from several different places when I need to work on it. HG usually has no problems, at least with 0.7.6 grids.
There might be some settings that are not turned on... maybe some obscure .ini settings for "allow external grids to create objects in user's folder" or something sinister like that, which didn't exist in 0.7.X. Still, I'd welcome any suggestion you might have. If all else fails, I think I can set up a region just with 0.7.6, join it to the grid, and see if that fixes the issue.
I'm pretty sure it's a problem just on our side, but any clues would be most welcome! They might even be posted on the Kitely wiki — sooner or later, many grids will migrate to 0.8.0 as soon as it becomes a stable release, and I'm sure it's important to make sure that marketplace delivery continues to work fine!
Thank you all in advance!
