Is there a standardized way to get the KVM (user interface) with just #ipmitool & co. Without any web, JVM, and/or proprietary apps?

Though I can run these in IceCat, via icedtea(-web), and a chroot/container/VM respectively, I expect the standards-based utilities, like `ipmitool`, to be enough for everything, not just a tiny subset of management tasks. Those vendor-specific apps really stink.
