How to use:

On Computer A: click Create Offer, then copy “My Blob” and send it to Computer B.
On Computer B: paste into “Remote Blob”, click Paste Remote Blob. B will generate its own “My Blob” (the Answer). Copy it back to A.
On Computer A: paste B’s blob into “Remote Blob”, click Paste Remote Blob. Connection should go Connected.
Now either side can select/drop files and click Send Selected.

Notes: NAT/firewall conditions can prevent direct connectivity. Works best when both peers can establish a path (often fine on normal home networks).
