Your reading is correct. Richard Stallman (among others) has been through the eCos license and has said that it was an acceptable "free software" license. This means that anyone can make a business out of eCos without paying royalties. The only shortcoming of the license is that there is no clause for GPL compatibility, so if you want to distribute an eCos kernel enhanced with GPLed code, you can't do it without getting various parties to make exceptions to their licensing. Grant> He also told me that eCOS is a revised version of another, Grant> older OS called Helos (or something like that). Nope: eCos was designed and developed from scratch. Some of the eCos designers might have been involved with Helios, but the design, goals and implementation of the OSes are completely different.
