|I think he's talking about an Apache server -- Wamp?? (window/apache/mysql/ and some p) ? |
If you're already using A M & P why not use linux too - PHP (for one) works much better in linux than windows. Just grab an Ubuntu install & use that. You can install it right from the package manager, no hunting for win32 apache binaries.
Unencrypted or VPN is up to you - how secure do you need it to be? What about just an SSL cert?
If I were you, I might look at some open source CRM solutions - rolling a custom solution like what you describe sounds difficult & time consuming.
SugarCRM is the the best open source CRM solution I've seen, the community edition is free. There's a demo over here: http://demo.sugarcrm.com (just hit login)
But, if you're using a WAMP server, you might as well just use IIS and then you can fully state that you are running a WIMPy server. (haha)
