I found two things that made me wonder. Now that BM is being sold it could be an issue. Both can be seen in these screenshots.

USPS logo. In their site titled Entertainment-Related Trademark & Image Use, it states “Want to use a U.S. Postal Service® trademark or image in your film or other media or do you wish to film on U.S. Postal Service premises? […] All requests for use of the U.S. Postal Service logo and other trademarks […] must be reviewed by the Rights and Permissions office.” I think there’s fees involved too.

Windows desktop with windows “My PC” and “Recicle Bin” icons and a Mozilla Firefox icon. I’m not sure if Firefox’s icon can be used in commercial works, but I suspect windows icons might bring trouble.
Enjoying your jungly Xen, btw.
