Okay I was able to re-compile 7.06 source, this time adding in a call to "buf_hexdump(vpninfo, (void *)bytes, sizeof(bytes));" right before those validation checks (oncp.c:654) ...that printed the hex to screen, which I copied to file then awk'd to remove the "0000: " prefix stuff. First 2 lines translated from hex were "MYHOSTNAME?"; I pasted 3+ in to an online Wireshark implementation at http://sadjad.me/phd and it did read some stuff correctly. Forwarded the hex dump on to my contact in the IT department to see if he can learn more from it. (No idea if this dump contains sensitive data, so holding off on posting here for now).
