Hmmm... I'm dubious. In that case, I'd suggest you want to attempt a larger approach to the problem:

• Dial up.
• log on.
• Dispatch previously prepared nodes
• Grab the list of newest nodes
• Download said nodes
• Update the newest nodes flag
• Drop phone line
• Edit responses off-line

Presumably, this is mutch the same way you handle your email? Or, a more accurate analogy: usenet?

While laudable, there are two problems with my above description:

• it's going to consume disk space like nobody's business. That's assuming you keep a certain quantity of nodes, for context, which isn't essential, but I suspect it'll rapidly become a requirement, even if it doesn't start as one.
• If you automate the procedure, then by the time your new nodes are posted (at, say, midnight your time), they may have been superceeded by on-line posters. Which isn't a problem <it>per se</it>, but may make your posts redundant

Sorry, this probably sounds more negative that I mean it to be: I actually think this is an interesting idea. I just think it might turn out to be somewhat bigger than you originally expect...

<bold>Update:</bold>Synchronously, blakem's just posted bivnn.cgi -- an alternate interface to newest nodes, which is probably worth taking a look at.
