We have an ASA 5500 linked to another site about a mile away (via extended ethernet fibre). We need some encryption on this link - typically AES. Is the only way to encrypt to use IPSEC/VPN Or can we encrpty the traffic in "less complex" way. Issues of performance matter too as there will be voice and time-critical apps running over this line too

The only wya you can encrypt the traffic is via some kind of VPN.

Not entirely true. You can place a hardware
crypto on both ends. Think of it like
encrypting the microwave signal. Doesn't have
to be VPN.

OK - I cant do a hardware option. So if I discount that - we are saying - either go for VPN solution - or not have encryption between the 2 locations ?

You can approach the problem this way:
Option #1: VPN
Option #2: encrypt at the application level
with either SSH or SSL encryption
Either way, the communication will be secure.
