Here's my implementation that doesn't seem to work... and I can't figure out why. Here's what happens when I use the below code: <url no longer valid>
Look at what's in the red markings. I'm assuming this is the break between user messages sent, but I can't figure out what exactly the problem is.

	void ShowMenu(int player_index, int seconds, unsigned int keys, const char *menu_string)
	{
		if (g_iShowMenu)
		{
			size_t len = strlen(menu_string);
			if (len < 251)
			{
				RecipientFilter rf;
				rf.RemoveAllRecipients();
				rf.AddRecipient(player_index);

				bf_write *msg = engine->UserMessageBegin(&rf, g_iShowMenu);
				msg->WriteShort((!keys ? (1<<9) : keys));

				msg->WriteChar(seconds);

				msg->WriteByte(0);

				msg->WriteString(menu_string);   
				engine->MessageEnd();
			}
			else
			{
				char menu_string_clamped [240];
				RecipientFilter rf;
				rf.RemoveAllRecipients();
				rf.AddRecipient(player_index);

				do
				{
					bf_write *msg = engine->UserMessageBegin(&rf, g_iShowMenu);
					msg->WriteShort((!keys ? (1<<9) : keys));
					msg->WriteChar(seconds);

					if (len < 251)
						msg->WriteByte(0); // Draw immediately
					else
						msg->WriteByte(1); // Draw later more info required

					snprintf(menu_string_clamped, sizeof(menu_string_clamped), "%s", menu_string);
					msg->WriteString(menu_string_clamped);   
					engine->MessageEnd();

					if (len > 250)
					{
						size_t s = strlen(menu_string_clamped);
						menu_string += s;
						len -= s;
					}
					else break;
				}
				while (len);
			}
		}
	}

OK.. I fixed it. Apparently you can only send a string about 230 characters long at a time, even though the other data in the user message takes up 4 bytes out of the 255.

Neat, I might be interested in this.
