[ale] Broadcasts on TCP/IP?

[Bob's ALE Mail]

Normally broadcast packets are sent in the UDP/IP protocol and
each responding host can send back information.

My question is:

Can broadcasts be used reasonable on TCP/IP given its connection orientation?

I searched the Linux kernel code and there seems to be support for it but
I suspect that the sender (sending the broadcast) would only be able to
talk with the first responding system?

Any thoughts?

Thanks,
Bob
