Sure. For example, hardware profiles are defined in the [EC2HardwareBuilder](https://github.com/jclouds/jclouds/blob/master/apis/ec2/src/main/java/org/jclouds/ec2/compute/domain/EC2HardwareBuilder.java), and then the [EC2HardwareSupplier](https://github.com/jclouds/jclouds/blob/master/apis/ec2/src/main/java/org/jclouds/ec2/compute/suppliers/EC2HardwareSupplier.java) is bound to the context and injected to the computeservice, so it can be used to list the existing hardware profiles.

This provides users a clean way to select a hardware profile. Something like:

```java
Template template = compute.templateBuilder()
    .fromHardware(EC2HardwareBuilder.t1_micro().build())
    .build();
```

It was just a suggestion, though. Having an object for each existing hardware profile (if they are fixed) is a good idea and can help.
