Chat plugin. Can I go mobile using it?

Hello WPMUDEV!

I am looking at adding a chat plugin to my website. The use would be for visitors to get in touch if they have questions etc... Now I am a one man show and am on the road sometimes. Is there any way I can answer chats while out of the office? I know some chat plugins connect to Skype and other messenging services. Hoping I can be connected at all times :wink:

Best regards,

Paul
