Yes, if your PC happens to be running Linux as its operating system; you can capture on the "any" device on Linux.  (PC != Windows, Apple's commercials to that effect nonwithstanding.)

Otherwise, you will have to open each device separately, and use either select() or poll() (NOTE: poll() won't work for pcap captures on any version of Mac OS X prior to 10.6) on UN*X, or WaitForMultipleObjects() on Windows (with WinPcap), to wait for one or more of the pcap_t's to have packets available.

No.
