This sounds like the perfect use case for our GBiB product, it is a fully self-contained UCSC Genome Browser that runs on your own personal machine.
After downloading the machine, you can share a folder with your BAM file in it, and then view your BAM file just fine! It sounds like you already have a web server set up though, so you can just give the LAN url on the custom tracks page within your gbib and that should work as well.
The GBiB is free for personal and academic use, and can be downloaded from our genome-store.
If you have any questions about the GBiB please feel free to send a question in to our mailing lists:
- firstname.lastname@example.org for general questions
- email@example.com for questions involving mirrors or gbibs
- firstname.lastname@example.org for questions involving private data
