customized strip down freebsd OS (less than 50MB)

[bsenthil]

Hi,

I am looking for mini freebsd customized OS (less than 50MB). Is it 
possible to customize the freebsd to below 50MB?

The list of modules i run over freebsd OS
1. TCP/IP stack
2. package installation.
3. File read and write operation
4. Apache server

What is the minimum size of the stripped freebsd OS ?

Please let me know detail/link how to customize freebsd OS.

Thanks,
Senthilkumar.
