Yes, you can use Radmin with 56kbps connection. Even if you are connected by modem, you can reach a
reasonable speed of about 5-10 screen updates per second. You will need to find out the real IP address your dial-up ISP is to assign to your laptop and connect to that IP address.
We are planning to develop Mac version of Remote Administrator, but now we are extremely busy with beta-testing of Radmin 3.0. The development of Mac version was not started yet. However, you can run Radmin under Virtual PC or other Windows emulator for Mac. Radmin has 30-day trial period, so you won't need to buy it to test is you would be able to run Radmin under Windows emulator for Mac.
Our developers beleive that including Redirect mode into RCS (and "connect through host" into RCC) will compromise security, since Redirect mode can redirect any type of Radmin traffic (including Full Control), so it would be possible to connect to any Radmin Server inside LAN through RCS.
There are several workarounds for this limitation:
1. Install RCS on a server that does have a real IP address.
2. If this is not a option, you can use port forwarding to forward all traffic on port 4897 from router to the server running RCS
3. If port forwarding is not a option, you can use Radmin Server to forward RCS traffic. In other words, you can connect to RCS through Radmin Server (which does support "connect through host").
RCS is not a replacement for Radmin 3.0, RCS is an another product!

Radmin Server 3.0 will also support Chat and Voice Chat features presented in RCS, but keep in mind that RCS will offer richer commuication capabilities than Radmin Server 3.0, since RCS is a specialized product.
WinXP SP2 enables built-in Internet Connection Firewall without letting you know. Built-in firewall blocks almost all incoming connections. You need to disable built-in firewall or re-configure it to allow incoming connections.
