Fulvio,
ZS is a wonderful router implementation with minimal memory/CPU/disk requirements, which works very well and has mostly intuitive feature rich administration interface.
But then comes the question: I have allocated a PC for ZS, which it uses only 10%. What more can I do with 90% left?
I know some managed to install Samba and use ZS boxes as file servers. But more could be done if we could get Jabber/SIP server, email, Apache, webmail, FTP etc.
Do you think it is possible to tweak ZS to use package manager like rpm to install those things into ZS?
Thank you!
